Wi-Fi has become a corporate necessity, but also poses increased risk. Unlike a hardwired network, the only requirement to intrude a wireless network is to be within range. Grantek helps our customers harness the benefits and control the risks of Wi-Fi. Automation companies develop software to run on everything from a smartphone to a desktop computer. For example, Rockwell Automation’s FactoryTalk VantagePoint Mobile and Inductive Automation’s Ignition Mobile Module, among others, are now developed for easy use on a smartphone. This means seamless coverage is necessary throughout a facility so that users will not experience shadow zones with low or nonexistent signal power. Unfortunately, factories can experience poor coverage for a number of reasons, ranging from Electromagnetic Interference (EMI) to shielding from the structure itself.
Grantek performs Wireless Site Audits including active and passive heatmapping to determine the best access point and antenna array placement in facilities. We conduct a discovery process to understand our clients’ true wireless needs and offer customers connectivity options that not only meet the needs of the manufacturing environment, but also operate within Corporate IT departments’ security processes, such as creating a Demilitarized Zone (DMZ) under the control of Corporate IT. Grantek’s stewardship of our customers’ Network Security means we ensure our customers are aware of the risk each wireless device can pose and educate them on the ways Grantek can mitigate those risks in an effort to maintain facility security at a high level.
Grantek creates segregated industrial wireless networks for our customers to help isolate manufacturing data from the rest of the corporate wireless network. Our experience in Wireless Mapping Studies enables Grantek to devise efficient solutions for providing wireless coverage in remote or hard-to-cover areas, such as inside large refrigerators or tracking trucks as they move through a facility’s parking lot.
